batch files

Batch files contain a sequence of DOS commands. By running the batch file, this sequence is run. This can be used to save time, so that a set of commands does not have to be typed out in full at the DOS prompt each time.

Batch files are text files, but with the .bat file extension. They can be created or edited with a text editor such as edit.

To run a batch file, simply type its name at the DOS prompt, with or without the .bat extension:

   c:\autoexec.bat
   foo
   foo.bat

A very important batch file, autoexec.bat, is run automatically when FreeDOS starts
